That's precisely why Einstein's theory of relativity was so groundbreaking. It stipulates that the speed of light must be the same relative to every frame.

Let's say you're moving nearly as fast as the speed of light. Are you flying side by side with light particles? No, because if they were, you would measure their speed as being close to zero relative to you. The theory says you will STILL measure the beams of light as flying away from you at the speed of light relative to you.

Imagine how the universe must conform to make that the case! The universe essentially makes your time tick slower in order for light to still travel that much faster relative to you.

This phenomenon has been confirmed (along with basically every other prediction that Einstein has made). There are some subatomic particles that we know has a half-life of X seconds. However, when they're traveling quickly, they actually end up living orders of magnitude longer because of time dilation.

In every day life, if you throw a ball at 70 mph on top of a car that's going 30 mph, the ball moves at 100 mph. You can't do the same math once you start reaching the speed of light.
"PSY's appearance on Ellen, SNL and The Today Show cause zero noticeable spikes"

Shouldn't be surprising in the least. The big network's dinosaur daytime show producers still treat the Internet and its culture as some "silly little thing" and only bother with it when something massive comes out of it...and by then they're the last to report on it.
The CAA is hosted and managed by archive.org; it is reasonable to expect that their lawyers greenlighted the project before hosting it. And for complains they already have a system in place to manage all the DMCA requests that they receive daily.

Only if you assume there's an inherent connection between the simulation and reality. I've written and run Conway's Life before, but because it was fun, not because it was an accurate simulation of reality.

In a world that has virtually unlimited computational power, who's to say there wasn't some teenager who got bored on the weekend and said "hey, what if I ran Simulation.app for 10 billion years of simulated time, but with only 4 fundamental forces, and 3 dimensions of space"?
First, I didn't mean to sound quite so negative on your project. I actually hope you succeed. If this is something the industry needs, I have no doubt you'll be a wild success.

I just take issue with raising money from unsophisticated unaccredited investors without even providing complete disclosure or binding contracts in return. I know a lot of companies do it, and I dislike it in those cases too. I also know I'm in the minority here and that it's only a matter of time before companies with huge VC backing & public companies are using Kickstarter to raise money. I think that's a bad thing, but others disagree.

Also, quickly:

- I'm not against for-profits using Kickstarter; most of the efforts there are for-profits. But companies that have raised millions of dollars probably should disclose that fact prominently in their campaigns.

- Similarly, the fact that you've been denied investment by >50 institutional investors is relevant in asking for money. It might be positive for some, negative for some. But it's likely not going to be a no-op for most.

- My figures come straight from Crunchbase, I'm not more connected than that.

4 Keys To Finding The Perfect Co-Founder
I feel you, my first laptop weighed close to 9 pounds with the power adapter. After that one, I picked either ultraportables or lightweight 14 & 15" models with a mid level graphics card. I bought a laptop for 1500 euros last month, and it isn't nearly in the ballpark of my 2 year old 600 euro desktop.
Kepler has 8 "SMX" with 196 parallel sp threads each. For me the number of cores = the number of parallel threads, although on GPU they are not as independent, i.e. each "core" of an SMX either executes the same instruction on adjacent data or does nop. With dual issue do you mean a two stage pipeline or two threads in parallel, both performing FLOP?

>> "one that will eventually have to be repeated"

> That's the point. With pg_reorg, you can easily partition tables on a daily basis ...

With all respect, partitioning active tables on a daily basis sounds like a very inefficient way to get around a problem with how the database is structured. It would be like pouring water into a car's radiator every day instead of fixing the problem at the source.

To me, partitioning a table that logically should be a single table, and that to users appears to be a single table, needs a different solution, something less hacky, like rethinking the basic database scheme.

Reasonable people may differ.
But from my own frame of reference all I would see is people frozen in time traveling a the speed of light, not really instantaneous. So in essence, the laws of physics have a built in hibernation mode for anybody traveling at c </joke>.
> Now if you have reached the speed of light, doubling the speed will never make you go back in time, it will just halve the time it takes you yet again.

It actually makes sense in that regard, because while accelerating, you will shrink along the acceleration vector.

Let's say you are 6 feet tall and fly Superman-style at 0.9c. You will then, from the outside, be 2.6 feet (or so). This means that if you from your timeframe accelerate by 1 km/s, to the outside you will accelerate by 0.4 km/s.

This acceleration in turn cause you to shrink even further, and as you approach the speed of light your external length will approach 0. So any further acceleration in your frame of reference, no matter how immense, would approach 0 from the outside.
As someone with nearly zero knowledge of statistics or Bayes' Theorem, I agree: the cookie problem was a very clear example to follow. The "Girl named Florida" solution, while interesting, probably doesn't work as well as a textbook example, at least not in that stage of learning.

Reading the Florida problem solution, it made some sense, but was definitely of a higher level of complexity than the rest of the text.

What I found really interesting was that the answers to some of the other questions on the "Girl Named Florida" discussion required knowledge which I would not have considered general math-ish knowledge:

> If the parents have brown hair
> and one of their children has red hair,
> we know that both parents are heterozygous,
> so their chance of having a red-haired girl is 1/8.

Interesting to learn, but this "if you also happen to know this ..." step is something that was mildly frustrating.

(edit: Since the grandparent post linked the Girl Named Florida blog post, I guess I don't need to.)

That's because their viewers are much the same.
If you were actually going the speed of light, light would still have to be able to go ~300kmh faster than you. To make this happen, time slows down for you.

That's what special relativity says - in any reference frame, light is always traveling v + c, where v is your velocity and c is the speed of light.

To make this happen, time itself slows down. But how would this actually work? Does this mean electrons would "orbit" within the electron cloud more slowly? (If not, then molecules larger than Z=137 may be possible.)
If the universe is a "computer simulation" running on the computer called the universe then a computer is a "computer simulation" running on a computer and we all are human simulations running on the computer called the human body.

Occam's razor would say that the simplest explanation is the best. Since this "simulation" works exactly the same as the known universe and we don't know about anything that is outside the universe, we can safely ignore this theory and not lose any information about how the universe works.

I tell everyone that I'm working on "a web page". Seriously. It's funny, and it starts the conversation off with a good, playful tone that makes it clear that I don't take myself too seriously.
Within your own frame of reference time slows down the faster you move. This is why from your own frame of reference light seems to always be moving at c no matter how close to c you get. Once you get to c time will be frozen. So if you travel for an entire year at c to you it will look like it was instantaneous, it wasn't, you could say you were "unconscious" the entire time. Somebody from a different frame of reference will notice you traveling at the speed of light and will notice that you are frozen in time.
*if you were actually going at the speed of light from a stationary observer, all travel becomes instantaneous from your reference frame.

the speed of light, c, can be violated from your frame of reference, but the external observer doesn't see this - it's your perception of time that has slowed down.

you reach the speed of light (from the perspective of an external observer) when your local velocity is infinite (and then all travel becomes instantaneous).
The logs sit on a ramdisk before being scrubbed; power removed before scrubbing? Logs are lost, but PCI compliance is maintained.
You have kind of contradicted yourself. "Seeing a big schema where all the tables look like ..." and "only about 58% of the tables will actually be named that way..."

So which is it? "All the tables" or "58%".

What you're trying to say is that inconsistency lights up the amateurs lights.

This sounds like a disaster waiting to happen...

You send them your own Raspberry PI, at your expense, for many probably over seas/out of country. You pay them nothing for their service. They're Yet Another Hosting Company.

Wait until you overuse some resources, they're late paying their data center bill (not sure how IP allocation work over there, but RIPE has their IP space, not them), you Pi for some reason goes offline, or the company goes under.

There is no free lunch. Just wait, it'll be proven again.
This actually included something I do: eat over the keyboard. I always keep a spare keyboard available, given that I first spilled tea into a keyboard around 1990, and have ruined many since then.

Yes, it's possible that a simulation would use a non-uniform lattice-like data structure. Maybe something like a quad-tree (with appropriate dimensionality) where the granularity of the structure varies according to the local density of data.

Granted, such a data structure would need to be expressed in a coordinate system, which itself defines a grid or matrix. But can't coordinate systems use non-uniform representations? (analogous to floating-point)

Am neither physicist nor CS person, so not sure all of this holds together, just wondering.
So I've covered all of these topics at some point in my career. What I'd love to see is someone like Coursera come out with a "what you should know as a computer scientist/software developer" curriculum...not only for myself, but for those who work for me. I would personally love to go back through a review of the various mathematics which are interesting for computer work, but I'd also LOVE to have a complete curriculum to put promising young developers through. You can teach concepts, but you can't teach attitude/demeanor (at least, not as easily).

I know Coursera has released bits of this sort of coursework, but I don't think they've put it in a guided, ordered curriculum form with preqs.

If someone puts this together, I'll gladly pay for it.

A question that has come up more and more lately with similar Kickstarter projects:

Is crowd funding a good way to go about this project? And specifically, is crowd funding through Kickstarter a good way to go about this project?

Basically, the project creator has an idea for a product for which he thinks there is a market, but he lacks the capital to get the business off the ground.

By using Kickstarter, he's able to acquire the capital, and the backers -- the vast majority of whom, I'm assuming, are either friends who just want to help him out or strangers who just want a bed-desk -- know that they'll get their money back if the goal isn't reached.

But once the goal is reached ... that investment becomes a risky investment. The obligation to actually deliver a product to those investors to whom it was promised is, at best, a moral obligation, rather than a legal one. Kickstarter has been very insistent on this point lately: If you donate to a project, consider it a donation, not a purchase (http://www.kickstarter.com/blog/kickstarter-is-not-a-store).

With more artistic projects -- say, a musician raising money to record an album -- I think it's a little bit easier to see those pledges as donations rather than purchases, even if a copy of the album is promised to donors. Why? For one, donors are likely to already be fans of the artist and feel a sort of kinship with them. But probably more importantly, the final cost of the album is likely to be in the $10-$20 range, which is a lot easier to write off, if the artist doesn't deliver, than an expensive piece of furniture.

In contrast, with a project like this, I'm assuming that if you're going to "donate" $650 or more, you're going to want a bed-desk at the end of it.

And at least on Kickstarter's current terms, the arrangement is not favorable to somebody who just wants a bed-desk at the end of it.

There may be other crowd-funding options out there that are more favorable to the would-be owners of a bed-desk (for instance, if the project creator were contractually obligated to deliver the product). Or perhaps the project creator could simply raise $65,000 with micro-loans, then sell the completed product to interested buyers, then use the proceeds to pay back the micro-loans. At least in that case, it's the aspiring businessman who's on the hook if something goes wrong, not the aspiring bed owners -- which is as it should be, because when an aspiring businessman is willing to take on financial risks, that demonstrates his commitment to the business. Or, if the project creator is not willing to take on all of that financial risk, perhaps he might be willing to offer equity in the business to potential crowd funders. That way, you're distributing the risk, but you're also distributing the potential upside, which is only fair, right?

As things stand, I just don't see a Kickstarter project for this type of product as being a good deal for anyone but the guy building the bed-desks ... unless you are willing to consider the $650 (or more) you donate to be just that: a donation.
How about NO?)

We suffix views with '_vw' and materialized views with '_mv'. This makes it easy to not have to consult the DDL every time we need to know what a table is. I've also run into several instances of:

object_name_mv
object_name_vw

I can only assume that at some point the view was non-performant for user-facing application and was turned into a snapshot.

In general, I'm a fan of suffixing views with '_vw' to basically be a red flag saying "there's another query behind me."
I'm assuming 'this' is any emulated device and not specifically Manymo (which I haven't tried -- I keep getting the "Fail Droid"). But there are plenty: you can't test bluetooth, get network state, check battery status, and other things.

But emulators are ok to test your layouts, even though the latest ADT plugin makes it much simpler with layout previews.

Can't you just put the monitor face down on the desk surface in most cases? Another alternative would be to mount the monitor on the duckboard or on the wall with a long flexible arm... THe latter option would provide a big screen TV to watch movies while lying on the bed... :)
I'm so out of touch with physics these days that I'm probably not even arm-chairing it correctly. But I still like to ponder crazy stuff...

I'd put my money on a hypothesis that says causality is enforced whether we can perceive it or not. Say we had such a computer with FTL circuitry. You attempt to instruct the computer to halt the current program when an answer is received, thus preventing the inputs being supplied that would produce the given output. Our current time-based perception says "paradox" whereas this proposed hypothesis would say "the computer simply will not halt the program," not because it's designed with safeguards, but because the laws of physics maintain causality.
You're implicitly assuming Newtonian mechanics and won't get anywhere until you stop. Here's an explanation of a simple thought-experiment based almost entirely on the assumption that the speed of light is constant that lets you easily derive time dilation: http://aeroja.blogspot.com/2011/01/moving-light-clock-ticks-...
I think it might be heading down the wrong path to talk in terms of "rational beings" as atomic units rather than in terms of energy (or rather information) balance.

Remember that you do live in a simulation of the universe so compressed it fits between your ears, and it does contain many simulations of other rational actors. They're nowhere near as complex as your whole universe, but I bet they're complex enough to know that they're complex enough.
> Partitioning can also be thought of a very compressed form of index, most of which are implement as some hierarchical data structure.

Yes, fair enough. In such a case, why not use an explicit index like letters of the alphabet, in other words why not reindex the table just once, hierarchically, with something relevant to table searches, in a way that breaks the table up into manageable chunks?

I'm only objecting to the idea of a periodic repartition -- it seems inefficient, and according to the linked article, it takes the table out of service for as much as 15 minutes, apparently on a daily basis. To me this sounds hacky and ad-hoc.

> To some extent, data reorganization is inevitable ...

Yes, but if the solution doesn't address the underlying problem, just the symptom, it will need to be reapplied perpetually.
That's the main reason I didn't short it - so many people seemed so invested in the IPO being a success, that I thought it would turn into a self-fulfilling prophecy. I'm surprised it fell so far and so fast; I think the trading glitch on NASDAQ took the bubbles out of the champagne for so many people that fiscal reality set in a lot earlier than it would have otherwise. Of course, going on the market at $38 didn't help, but their pricing strategy was sort of constrained by activity on Second Market.

>>But how would this actually work? Does this mean electrons would "orbit" within the electron cloud more slowly?

Yes, all of the particles within that frame of reference slow down. Why? Who knows. Maybe space becomes more "viscous" which slows down all particles within it.
I think the key question is really "are you basically ready to turn this into a registered company?" If you aren't, then it's not a startup.

More importantly, you don't "work on a startup". You work on a project, a product, a service, an idea. If you're working on a startup, you're hopefully a consultant of some kind: legal, HR, whatnot.

It's okay to say "I work at a startup." But that's really less than useful information for both you and the person you're talking to. It's about the same value as "I'm an Asian-American." Congrats, you qualify for a scholarship. Cookie? At least say "I'm an engineering major." or "I'm doing mobile."

Does this, literally, mean anything at all? I struggle to find any significant value in having this knowledge. Are there any additional conclusions we can draw based on knowing that the universe is a 'simulation of itself'?

It just strikes me as tautological.
